Solution or Workaround

   • At 9.3, it is recommended that a repair is run on the ArcGIS Desktop install.
   
   A) To run a repair, insert the ArcGIS installation disk.
   
   B) Click Exit and navigate to Start > Settings > Control Panel > Add or Remove Programs. Select ArcGIS Desktop and click the Change button. When prompted, select the Repair option.
